In late 2021, Cardno now Stantec was engaged to identify potential drilling targets and obtain Virginia Department of Health (VDH) well site approvals. In February 2022, a well was drilled at one of the selected locations and yielded no water. The purpose of this memorandum is to present our professional opinion on the feasibility of operating an on - site groundwater supply system based on existing documentation and knowledge of the property's water system and the hydrogeologic setting. Water System History The property's water system has historically sourced water from four (4) groundwater wells (Figure 1). Well construction information presented below was obtained from the Charlottesville Moose Lodge Virginia Department of Health (VDH) Engineering Description Sheet for VDH Waterworks Operation Permit (WOP) #2003203 (2006; Attachment 1). Well 1 was constructed in 1972, is 300 feet deep, and reportedly yielded 1.5 gallons per minute (gpm) at the time of construction. Steel casing extends to 20 feet below land surface (bls). Well 2 was constructed in 1988, is 300 feet deep, and reportedly yielded less than 1 gpm at the time of construction. PVC casing extends to 20 feet below land surface (bls). Well 3 and Well 4 were installed at an unknown time prior to 1972. Well construction information below land surface is unknown, but both wells are reported to have a "very low yield". On July 28, 2015, VDH revoked the property's WOP, citing continually poor water quality and low well yields, among other concerns (Attachment 2). One of the requirements for issuing anew WOP was to "secure an acceptable water source that is capable of providing adequate quantity and quality of water...". In February 2022, Well 5 (Figure 1) was constructed. The well is 400 feet deep and reportedly yielded no measurable water. Hydrogeology Beneath the property, a relatively thin layer of soil and saprolite (in -situ weathered bedrock) overlies Candler Formation phyllite and schist bedrock of Cambrian age (1993 Geologic Map of Virginia, Virginia Division of Mineral Resources). Candler Formation groundwater flow is almost entirely limited to areas of hydraulically connected secondary porosity, created by faulting and fracturing of bedrock. Wells constructed in fractured -bedrock aquifers only yield sustainable quantities of water if they intersect fractures which 1: contain water, and 2: are hydraulically Australia • Belgium • Canada • Colombia - Ecuador • Germany • Indonesia Kenya • New Zealand • Nigeria • Papua New Guinea • Peru • Philippines • Singapore United Arab Emirates • United Kingdom • United States • Operations in over 100 countries March 3, 2022 Mr. Trevor Hammer Summary of Groundwater Resources — Former Charlottesville Moose Lodge r„•i Cai-dn0 ^�w Stantec Parcels 79A7-B-24, 79A1-B-25, 79A1-B-27, Albemarle County, Virginia connected to a source of recharge, such as the land surface or the bedrock contact with soil or saprolite (through the infiltration of precipitation). In 2003, ENSAT Corporation and Albemarle County prepared a Groundwater Availability and Sensitivity Assessment with Proposed Groundwater Assessment Standards as part of the Albemarle County Hydrogeologic Assessment Report. Of note in this report is that the Candler Formation is "generally more ductile than other rocks in the County, meaning that fractures can close up due to the weight of overlying material'. A result of this is a decreased likelihood of wells intersecting water -bearing fractures. This fact, in conjunction with other analyses, resulted in the Candler Formation being categorized as having the "Lowest Relative Availability" of groundwater. Conclusion Five (5) wells have been constructed on the 6-acre property, none of which yield water of sufficient quantity and quality for the property's former use ("clubs and lodges" by Special Use Permit), the proposed by -right use ("religious assembly of not more than 200 persons"), and other non-residential by -right uses. Excluding the development footprint and drainfield areas, the area available for wells is less than 5 acres. The wells are each 100 feet or more from each other, spatially covering a large portion of the property, and are located on differing slope aspects, topographic features, and elevations. Obtaining groundwater from the Candler Formation is well-known to be a challenging and uncertain process. Given the evidence of poor water quality and yield from the property's existing wells and the geology, it is our opinion that the property has been sufficiently investigated, obtaining an adequate groundwater well is unlikely, and an alternate source of water would be more feasible, such as obtaining a connection to public water.
